High-spin tetranuclear iron(III) grids: Synthesis, crystal structure and magnetic properties

Three new tetranuclear FeIII complexs Fe4L 14Cl4 (1), Fe4L2 4(ClO4)4 (2), Fe4L3 4Cl45H2O (3) and a binuclear complex Fe 2L4(MeOH)2Cl43MeOH (4) (the bis-Schiff base ligands H2L1-4 were obtained by the condensation of 2,4-dihydrazinopyrimidine and salicylicaldehyde or acetylacetone in a molar ratio of 1:2) have been synthesized and characterized by crystallography, spectroscopy and magnetic measurements. The tetranuclear 2 × 2 grid complex 1 crystallizes in a monoclinic space group C2/c with a = 29.040(3) A?, b = 10.9525(11) A?, c = 26.881(3) A?, β = 105.172(2)°, V = 8251.9(15) A?3. Complex 2 crystallizes in a monoclinic space group P21 with a = 12.536(3) A?, b = 23.148(5) A?, c = 17.506(4) A?, β = 102.96(3)°, V = 4950.6(17) A?3, and complex 3 in a triclinic space group P1? with a = 12.145(2) A?, b = 29.094(6) A?, c = 29.343(6) A?, α = 94.12(3)°, β = 93.17(3)°, γ = 97.62(3)°, V = 10228(4) A?3. All the FeIII ions from 1, 2 and 3 are coordinated by an N4O2 sphere with two N atoms from pyrimidine, two N atoms from hydrazine, and two O atoms from phenoxo groups. Complex 4 has a binuclear structure crystallized in a triclinic space group P1? with a = 10.500(2) A?, b = 11.053(2) A?, c = 15.990(3) A?, α = 82.20(3)°, β = 89.64(3)°, γ = 70.77(3)°, V = 1734.4(6) A?3. Magnetic susceptibility measurements indicate that the Fe(III) ions are all high spin, and adjacent Fe(III) ions are weakly antiferromagnetically coupled via pyrimidine in complexes 1, 2, 3 and 4. Magneto-structural correlation studies show that a longer Fe-Npym bond distance corresponds to a weaker antiferromagnetic coupling.
